AUTOMOBILE-RADIATOR.

Specification of Letters Patent.

Patented Nov. 8 1910.

To all whom it may concern:

Be it known that I, JACOB FLEISCHMAN, a citizen of the United States, and residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Automobile-Radiators, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make and use the same.

This invention relates to water coolers for automobiles otherwise known as radiators, and the object thereof is to provide an improved device of this class together with the g l'eatest possible radiating qualities whereby t e water used for cooling the engine may be freely circulated and kept at the lowest possible degree of tem erature.

The invention is ful v disclosed in the following sgecification of which the accompanying rawing forms a part in which the separate parts of my improvement are designated by suitable reference characters in eachof the views, and in which Figure '1 is a partial front end view of a radiator of an automobile made according to my invention with part of the-construction broken away; Fig. '2 a section on the line 22 of Fig. 1; Fig. 3 an end view of the method of connecting the separate parts or units of which the radiator is composed; Fig. 4 a side view of one of the separate parts or units of the radiator, and ;.Fig. '5 an enlarged diagrammatic sectional view of my improved radiator, the line of the section being that indicated at 55 in Fig. 2, and

1 showing th passages in the radiator through which the ater circulates.

In the drawing forming part of this s ecification I have shown at a, the frame 0 the radiator usually employed by automobiles, and this radiator comprises a top member a and bottom memberia connected by side members a. The top member a forms a chamber a and the bottom member a forms a chamber a and communicating with these chambers are pipes a and a which in'pra-ctice are" connected with the engine In the usual manner and through which the water circulates or passes to and fromthe engine as indicated by the arrows m and w in Fig. 1, andthe top chamber a of the radiatoris provided with the usual filling aperture or opening a, through which the water is passed into the radlator.

The body portion of the radiator is made up of se arate units 6 composed of sheet metal an comprising a lurality of tubular members b preferably our in number connected by web members b, said tubular members and web members being arranged in the same plane or in a plane pass ng through the axis of the tubular members. The end portions of the tubular members 6 are hexagonal in form, as shown at b and the bod portions of said tubular members are pre erably elliptical incross section, the transverse dimensions thereof being less than the transverse .dimensionsof the end portions I), this construction being clearly indicated at b in Figs. 3 and 4.

The se arate units 6 of the radiator are formed rom tubes of thin metal such as brass, copper or other suitable metal, or from sheets of metal folded together and the'ends thereof soldered, and the web portions 12* of said units are thus made of two thicknesses.

The separate. units 6 are connected in transverse series to form the body of the radiator as shown in'Fig. 3, the, alternate units of each series being arranged one step lower than the others, and in practice two or more of these series are placed together one above another, as indicated in Fig. 5, and the end portions 6 of the se arate units of the radiator are connected -w en placed to-.

ther in the manner shown and described y soldering in the usual way, and when the said unitsare connected in this manner and the end portions thereof soldered together there are four thicknesses of metal at b" where the end of the tubular members I) connect, said four thicknesses being formed by the web portions 6 of the separate units,

and two thicknesses at-Zfi; in other words four of the sides of the tubular member b or the endsb' thereof are of two thicknesses, while the other two sides are of fourthicknesses and this insures, when the end portions of said separate units b v are soldered togethe r,a' strong and substantial construc 'tion. i

It', will be understood, that, in practice the water enters the chamber b at the top of the radiator and passes downwardly through the radiator or between the se arate tubular members thereof as indicated by the arrows y in Fig. 5'. In this operation the water passes between the first transverse top row again divided at c and continues on down to the bottom of the radiator where it enters the chamber a.

From the foregoing description it will be seen that the chief characteristic of my improved radiator is that the body portion thereof through which the water passes downwardly is composed of separate transverse series of units, one of which is placed above another, the separate units being made up of separate tubular members connected by web members, said units being placed together side by side with the alternate units one step lower than the others. The end portions of the tubular members of said units being larger than the body portions thereof whereby passage ways are formed between the separate units in each series, and said end portions being hexa onal in form and soldered together. It wiIl be apparent that a radiator'made in this manner may be of any desired dimensions or capacity and any desired number of series of units may be employed, one above another, and any desired number'of similar units may be placed in each series.

In practice the air passes from the front of the radiator backwardly therethrough or through the tubular members 6 of the separate units and as the water passes downwardly between the separate units of the radiator or the separate units of the separate series of units which constitute the radiator,

and is divided up in its passage as herein. -P

described, it is quickly and easily cooled, the motion of the automobile facilitating the passage of the air through the radiator as in all other devices of this class.

Having fully described my invention,

what I claim as new; and desire to secure by Letters Patent, is;

1. A radiator of the class described, composed of a plurality of sheet metal tubular units each having expanded hexagonal ends with an intervening portion of elliptical form, said central portlons being separated by a web portion of two thicknesses of the metal, the said ends of the units being nested together and securely united, the said central portions of said members forming undulating or tortuous curved passages from top to bottom, such passages being closed at each side by the united expanded portions of said units, the union at the points at whichuthe web portions are united with adjacent parts consisting. of four thicknesses of metal.

2. A radiator of the class described, composed of a plurality of sections of sheet metal tubular units each having expanded hexagonal ends with an intervening or central portion of elliptical form, said central portions'of the tubes being separated by a web of two thicknesses of metal, the said ends of the units-being nested together and securely united, leaving passages between the central portions, the union at the points at which the web portions are secured to adjacent portions consisting of four thicknesses of metal, the said radiator having one or more sections in vertical alinement, the said passages being merged or connected by a space intervening between the alined sections, the united enlarged hexagonal portions forming the closing of said passages at the sides.

In testimony that I claim the foregoing as my invention I have signed my name in 16th day of December 1909.
